What term refers to 'The house of the gods'?

The term that refers to 'The house of the gods' is Valhalla. In Norse mythology, Valhalla is depicted as a grand hall located in Asgard, where warriors who have died bravely in battle are welcomed after their deaths. These warriors are chosen by the Valkyries, who carry them to this magnificent hall.

Valhalla is often described as a place of honor and glory, where the slain heroes live under the rule of the god Odin. Here, they prepare for the final battle of Ragnarök, feasting and training for this ultimate confrontation. The significance of Valhalla underscores themes of bravery, heroism, and the afterlife in Norse culture.

The other options refer to different aspects of Norse mythology: Wotan is another name for Odin; Brünnhilde is a character associated with Wagner's operas, not specifically a dwelling; and Valkyrie refers to the warrior maidens who serve Odin and select the slain for Valhalla, rather than the hall itself.
